To all whom t may concern.-

Be it known that I, `WILLIAM H. KELL, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinols, have invented certain new and useful mprovements inAdjustable Posts for BindertIon.

This invention relates to posts for use in connection with binder-les employing adjustable locking binder-bars; and the present invention is intended to provide a post l` Files, of which the following is a specifica- N which will enable the binder-bar to be raised and the files slipped into place without ex-V tending the entire post to allow for the raising of the binder-bar, the entire device in i use being simple and compact, occupying but aslight amount of space,iand being adapted for use with le-binders of varying capacity.

The invention consists in the features of construction and combinations of parts hereinafter described and claimed.

In the drawings, Figure l is a side elevation of an ordinary file-binder employing a binder-bar; Fig. 2, a similar view showing the cover raised; Fig. 3, a" rear end `elevation of the file-binder of Figs. l and 2; Fig. et, a

`portion of `a file,

showing the nature of the `hole andyslot therein; Fig. 5, a side elevation of thepost'closed; Fig. 6, a similar view showing the post open; Fig. 7, a view show-` Figs. 8, 9,and

The extensible post, which more particularlyA forms thesubject-matter of this invenby means of a screw-threaded binder-bar B, of any well-known construction, operated by means on model.)

stud c', and said socket is provided with a recess c, into which is screw-threaded the tud cl of the fixed section D of the extensi-V ble post. The lixed section is provided with a slotted tongue d, having side walls d2 and a cross-head d3, as shown in Fig. 8, which tongue is of the same width as but of less diameter than the body of the fixed member. A movable member E of the same diameter as the fixed member consists of a body portion e and a slotted portion e', which slotted portion fits over the slotted tongue on the fixed member and is held thereon `and prevented from being withdrawn therefrom by means of a crosspiu e2. (Best shown in Fig. 9.) rlhe extensible member is provided on itshead with a screw-threaded recess e3, into which is screwed the studfof the head F, as shown in Fig. 9. Around the fixed and movable members is a sleeve or casing G of a shape, as shown, to conform to the curvature of the members, although it is obvious that the latter might be madesquareorangularratherthanround. In order to prevent withdrawn from the casing or sleeve, a pin g is passed through the fixed member and the sleeve or casing, holding the two into firm and rigid contact with one another and preventing the withdrawal of the fixed member.

In Fig. lla slight modification of the arrangement hitherto described is shown in which the slotted tongue of the fixed member is dispensed with and a cross-pin J inserted to take the place of the cross-head cl3 of the tongue. is the same as that hitherto described, and the only dierence in construction is that the side walls d2 of the slotted tongue are dispensed with, making the structure less rigid and substantial than that hitherto described.

In Fig. l2 is shown a post provided with an intermediate section H, which latter is inserted between the extensible post and the `socket and is provided with a stud `It and a recess h', the former of which screws into the socket and the latter of which receives the stud on the fixed member of the extensible post.

the fixed member from being p The extensible member in this case In Fig. 13 is shown a section adapted for use with the post in its extended relation. The section consists of a cylindrical tube I of the same diameter as the sleeve or casing, within which, at the outer end thereof, is a plug t, from the inner face of which projects a stud t", and in the outer face of which is a recess t2, into which may be screw-threaded another section of a head if so desired. The plug is held in place within the tube by means of a pin t3 passing therethrough. The section last described enables the extensible post to be extended and virtually formed into a slotted post by the simple operation of screwing the section thereonto, thereby greatly enhancing the value of the extensible section and increasing its adaptability to varying conditions.

The files are provided near their edge with holes K of a diameter to encircle the posts, and a slot 7c is cut to the edge of the file, thereby enabling the same to be slipped onto the side of the post instead of over the top.

In use the files are slipped onto the post and the upper cover, carrying the binder-bar, broughtdown tightlythereonto. Thebinderbar is thenlocked onto the post, which tightly clamps the same, and said clamping `operation may be made to slightly compress the sleeve or casing, thereby contacting the clamping and movable section within and preventing the Withdrawal or displacement of the movable section as long as the binder-bar remains locked. When it becomes necessary to insert new files into the binder, the binderbar is unlocked, releasing the movable section within the casing and allowing the movable section to be withdrawn, as shown in Figs. 2 and 3, whereby the binder-bar and upper cover may be raised from the sleeve or casing up into position upon the movable section, releasing the pressure on the files and allowing additional files to be inserted into place. When the latter have been inserted into place, the upper cover is again brought down thereonto, causing the binder-bar to once more encircle the sleeve or casing. The movable section is then pressed down into the sleeve or casing and the binder-bar is locked thereonto, compressing the sleeve or casing and clamping the movable section in place. The operation in respect to the post of Fig. ll is .precisely the same as that hitherto described. If the size of the file is so much increased that it becomes necessary to lengthen the rod, such a result may be accomplished either by means of an intermediate section, as shown in Fig. 12,A or by means of an exterior section, as shown in Fig. 13. In the latter case it will not be necessary to remove the les from the extensible post, but the exterior section may be immediately inserted thereonto, transforming the extensible post into a substantially solid post, onto which may be fitted another extensible post, if so desired. In this way the length of the post may be indefinitely increased without removing any of the files from the binder or disturbing them in any Way.

What I regard as new, and desire to secure by Letters Patent, is-

l. A post for binder'- binder-bars, which consists of a fixed section, a slotted movable section provided with a stop or abutment closing the slot, a sleeve or casing xedly attached to the fixed section, and an abutment extending across the shell or casing through the slot in the movable section and adapted to contact with the stop or abutment in the movable section and prevent the withdrawal thereof, substantially as described.

2. A 'post for binder -files which employ binder-bars, which consists of a fixed section terminatingin a screw-threaded stud and provided with a slotted tongue, a slotted movable section adapted to inclose the tongue and provided with a pin or stop passing throughthe slot in the tongue to prevent the withdrawal of the movable section therefrom, a sleeve or casing fixedly attached to the xed section inclosing the fixed and movable sections When in retracted relation, and ahead on the movable section, substantially as described.

3. A post for binder-files whichl employ binder-bars, which consists of a fixed section provided with a slotted tong-ue, a movable section having in its body a slot adapted to inclose the tongue, a pin or stop passing through the ends of the slotted movable section preventing the withdrawal of the movable from the fixed section, a sleeve or casing within which the fixed section is ixedly held, and a head screw-threaded into the end of the movable section, substantially as described.

4t. A post for binder-files which employ binder-bars which consists of a fixed section terminating in a screw-threaded stud and provided With a slotted tongue upwardly extending, a sleeve or casing within which the iixed section is fixedly held, a slotted movable section adapted to inclose the tongue and provided in its end with a screw-threaded recess, a pin passing through the end of the movable section preventing its withdrawal from the iixed section, a stud screw-threaded into the recess in the end of the movable section, and a shell or casing of the same diameter as the sleeve or casing within which the stud is fixedly held and of a length to contact the end of the sleeve or casing when the extensible section has been forced downward to its-limit, substantially as described.
